'2, 3*aiid '4; The stripisthen bent longitudinally upon itself to channel shape in cross section with the sid'e -wallsgl0, 11 of the channel" co n erging toward" each other in a direction" from. the body of the'strip, es

shown in Figs. 3 and 4,.and the teeth'extending from the bodyofthe strip in' a direction opposite to the side wallssof the channel.

Simultaneously with the bending of the 1 strip to channel shape, or previously thereto, the strip is; shaped to circular; form.

After the strip has been formed asset forth the same is subjected to a hardening process.

As stated it is the object of the invention v to provide a toothed member adapted to be I removably mounted upon a carrier or carriers in a cotton gin or linter, and in Figs. 6 and 7 I have shown a type of a saw cylin: der to which my invention is applicable, consisting of a series of disks 12v having a central opening for the engagement of ashaft 13 upon which the disks, are mounted in juxtaposed and spaced relation to rotate with the shaft and have axial adjustment thereon by a key 14c engaging in key-ways in the respective disks and shaft and are held against endwise movement by washers 14 and nuts 15 threaded onto the ends of the shaft. The channel toothed members are mounted upon the periphery of the disks with the teeth to extend radially from the periphery of the disks as clearly shown in said Figs. 6 and 7..

fasteningmeans or the like the peripheral portions of the disks in opposite facesfare provided with annular recesses 16, 17,the walls of-which recesses converge or incline inwardly from the periphery ofthe' disks and the inclination ofthe walls of the recesses being substantially the same as the inclination of the channel walls of the toothed member. The toothed member having been hardened the channel walls will be springy' oryieldable having an inherent tension to: spring inward and will give'sufiiciently to readily place them in position :upon the'pev riphery of thedisksyandwhen placed upon the disks will 'operate to clamp and firmly hold said membersto the disks. While these toothed members are preferably'made of a number of segments to extend around the peripheryof the disks, it will be obvious they may comprise a single and continuous member. T w

Having thus describedmy 1nvent1on,'-I cla1m:'

laThe method ofimaking toothedmein-ibers, consisting in stamping angular portions from a strip of material with the apex of alternate" portions extending in opposite directions toward the lateral edges of the strip and the bases extending in a line longitudinally of and centrally between the lat eraledges of the strip, and then bending such angular portions to extend laterally from the body portion of the strip.

2. The method of making toothed members, consisting in making angular incisions in'theshape of saw teeth in a strip of material with the basesof the incisions com To look the toothed members to the pe riphery of the disks and permit of the re moval'oi the same without the loosening of mencing in a line extending longitudinally of and centrally between the lateral edges of the strip and alternate incisionsextending in opposite directions from such line, and bending the portions severed within such incisions to extend laterally of the body portion of the strip. a

3. The method of making toothed members consisting in making angular incisions in the shape of saw teeth in a strip of mate- 'rial with the apex of; alternate incisions extending in opposite directions toward the lateral edges of the strip, and bending the lateral edges of the strip, bending the por,-

tions withinsuch incisions toextend laterally from the strip, andbending the strip substantially to channel shape in cross section with the free ends of the walls converging towardeach other for the purpose specified.
